Analysis of Heat Shock Protein 70 Expression, Caspase 3, and Microbiota Composition in Colorectal Cancer Patients

Introduction

Colorectal cancer is one of the most common types of cancer worldwide, ranking fourth after other cancer types and second in the United States. In Indonesia, reports from various health centers show an increase in the number of cases of colorectal cancer every year. This study aims to develop early detection candidates for colorectal cancer in patients in Indonesia. The research focuses on analyzing the expression of Heat Shock Protein 70 (HSP70) and Caspase-3 and microbiota composition in Colorectal Cancer Patients (KKR) compared to colorectal non-cancer patients in Aceh Province.

The Importance of Early Detection in Colorectal Cancer

Early detection of colorectal cancer is crucial in improving the prognosis and quality of life of patients. Colorectal cancer is a type of cancer that develops in the colon or rectum, and it is often asymptomatic in its early stages. If left undetected, colorectal cancer can progress to more advanced stages, making treatment more challenging and reducing the chances of survival. Therefore, developing effective early detection methods is essential in reducing the mortality rate of colorectal cancer.

Research Purposes

This study aims to analyze the expression of HSP70 and Caspase-3 and microbiota composition in Colorectal Cancer Patients (KKR) compared to colorectal non-cancer patients in Aceh Province. This analysis is important to understand the relationship between protein expression and microbiota composition in the context of cancer. The study also aims to identify potential biomarkers for early detection of colorectal cancer.

Research Methods

Some methods used in this study, including histopathological analysis with hematoxylin-eosin (HE) coloring to observe tissue morphological changes, as well as immunohistochemicals to measure HSP70 and Caspase-3 expressions. In addition, the isolation of DNA feces and PCR-DGGE analysis is carried out to evaluate the composition of microbiota in 16 patients with colorectal cancer and 16 colorectal non-cancer patients.

Histopathological Analysis

Histopathological analysis is a crucial step in understanding the morphological changes in tissues. In this study, HE coloring is used to observe tissue morphological changes. The results show that in colorectal cancer patients, there are significant changes in tissue morphology, including the presence of cancer cells and the loss of normal tissue structure.

Immunohistochemical Analysis

Immunohistochemical analysis is used to measure the expression of HSP70 and Caspase-3 in tissues. The results show that in colorectal cancer patients, HSP70's expression increased significantly, with the highest score reaching 8, while Caspase-3 expression decreased, with the highest score of only 5. Conversely, in non-canker colorectal patients, Caspase-3 expression has a score The highest is 8, while HSP70 only reaches the highest score of 5.

PCR-DGGE Analysis

PCR-DGGE analysis is used to evaluate the composition of microbiota in feces. The results show that all colorectal cancer patients show the loss of dominant bands from the Bifidobacterium group. This suggests that the loss of Bifidobacterium is a potential biomarker for early detection of colorectal cancer.

Conclusion

From this study, it can be concluded that the expression of HSP70 is contrary to the expression of Caspase-3, and the loss of bifidobacterium in colorectal cancer patients can be used as an important indicator in early detection of colorectal cancer in Indonesia. This knowledge has major implications in the development of prevention and early detection strategies, which are essential to improve the prognosis and quality of life of colorectal cancer patients in this country.

Future Directions

This study is expected to be the basis for further study in understanding the relationship between protein expression, microbiota composition, and the development of colorectal cancer. With a deeper understanding, it is hoped that we can find more effective methods in early detection of colorectal cancer that is increasing in Indonesia. Further studies are needed to validate the findings of this study and to explore the potential of HSP70 and Caspase-3 as biomarkers for early detection of colorectal cancer.

Implications for Clinical Practice

The findings of this study have significant implications for clinical practice. The identification of HSP70 and Caspase-3 as potential biomarkers for early detection of colorectal cancer can lead to the development of more effective screening methods. This can help in reducing the mortality rate of colorectal cancer and improving the quality of life of patients.

Limitations of the Study

This study has some limitations. The sample size is relatively small, and the study is limited to patients in Aceh Province. Further studies are needed to validate the findings of this study and to explore the potential of HSP70 and Caspase-3 as biomarkers for early detection of colorectal cancer in other populations.

Conclusion

In conclusion, this study provides new insights into the relationship between protein expression, microbiota composition, and the development of colorectal cancer. The findings of this study have significant implications for the development of prevention and early detection strategies for colorectal cancer. Further studies are needed to validate the findings of this study and to explore the potential of HSP70 and Caspase-3 as biomarkers for early detection of colorectal cancer.
